(not the) Agnus Dei

I have extended the Agnus Dei significantly, adding new verses with the words: Quoniam tu solus Sanctus, to Solus Altissimus Jesu Christe/For thou alone art holy, Jesus Christ; cum Santo Spiritu in gloria Patris… I have used a tune which, originally, I had as a counter melody to the main Agnus Dei theme, but which I decided not to use.

I am not at all sure that extending this piece really works… Something else to mull over.
